Description

[0001] The present invention relates to a device for closing a motor vehicle cooling module and to a motor vehicle comprising a device for closing a motor vehicle cooling module.

[0002] In modern vehicles, especially cars, fresh air entering through the vehicle's radiator grille or its openings is channeled and directed onto a cooling module. This targeted channeling of the airflow to the cooling module ensures that, depending on the module's design, the vehicle's engine and / or charge air for that engine can be efficiently cooled, and / or the vehicle interior can be efficiently air-conditioned.

[0003] Unfortunately, the incoming airflow creates turbulent flows that counteract the movement of the vehicles in question and lead to reduced range or increased fuel consumption. To solve this problem, roller shutter systems are known from the prior art, e.g., from US 2020 / 0 156 461 A1, DE 10 2019 106 828 A1 and DE 10 2019 106 826 A1, which can close the air inlets located within the engine compartment when necessary and thus reduce the generation of turbulent flows.

[0004] In the context of on-demand opening and closing of air intakes located within an engine compartment, systems have become particularly established that are also capable of closing, as needed, only symmetrically arranged sections of a vehicle interior on opposite sides along the width of the vehicle, in order to separately close the brake air ducts located on the outer edges of the front of many vehicles. Such a system is known, for example, from DE 10 2019 117 986 A1.

[0005] Disadvantageously, the system known from DE 10 2019 117 986 A1 has a large number of interconnected components, which not only increases manufacturing and maintenance costs but also complicates operation, particularly the coordination between the individual components. Furthermore, the interconnected components of the known system must be located at least partially centrally behind a radiator grille, which is not only disadvantageous in terms of installation space but also results in the inflow of fresh air being obstructed when such a roller blind system is open.

[0006] It is therefore the object of the present invention to at least partially overcome the aforementioned disadvantages of known closure systems. In particular, it is the object of the invention to provide a device for closing a motor vehicle cooling module that enables, in a simple and cost-effective manner, the opening and closing of air inlets arranged along the width of a vehicle in a controllable and flexible manner, thereby enabling both effective ventilation of the vehicle interior and effective prevention of turbulent flows.

[0007] The foregoing problem is solved by a device having the features of the independent device claim and by a motor vehicle comprising a device according to the invention as per claim 22. Further features and details of the invention will become apparent from the dependent claims, the description and the drawings.

In particular, via the opening provided according to the invention from the center of the vehicle to the outer areas of the vehicle, respectively...Furthermore, by closing the vehicle outer areas towards the vehicle center according to the invention, it is possible to supply only a centrally arranged vehicle front area with cooling air and, for example, to exclude brake air ducts arranged exclusively in the side areas of a vehicle front from ventilation, which has proven advantageous for some applications.

[0011] Furthermore, it has been recognized within the scope of the invention that the arrangement and controllability according to the invention, in particular the fact that the first control element is arranged on the first guide element and the second control element is arranged opposite the first guide element on the second guide element, wherein the first control element is connected to the second closure element and the second control element is connected to the first closure element in such a way that the first closure element can be controlled via the second control element and the second closure element via the first control element, results in a particularly simple and cost-effective arrangement that guarantees not only optimal ventilation but also effective elimination of turbulent flows.The arrangement according to the invention makes it particularly possible to minimize the number of necessary components, so that the device can be operated with only two control elements and preferably only one drive unit. Furthermore, the arrangement makes it possible to position the control elements preferably on the outer surface of the device, on the guide elements or on the outer surface of a vehicle's front end, thus utilizing the available installation space and leaving a central space free for effective ventilation.

[0012] In accordance with the invention, to enable the opening and closing movement to be controlled as precisely as possible, it is advantageously provided that the first and second control elements are arranged symmetrically to each other, with the center of symmetry preferably located centrally between the guide elements, in particular at half the height of the locking elements. In such an arrangement, the control elements provided are preferably arranged diagonally to each other with respect to a front or rear view.

[0015] According to the invention, in the context of a structurally simple and reliable fastening of the locking elements to the control elements, it can advantageously be provided that the locking elements have end-mounted recesses for fastening, preferably a plurality of recesses arranged one above the other, wherein the recesses are designed in particular for the insertion of receiving ribs of end strips.

[0016] With a view to a space-saving and compact arrangement as well as an effective and low-wear guidance of the locking elements during an opening and a closing movement, the invention may also provide that the guide elements are formed in the form of winding shafts onto which the locking elements can be wound during an opening movement and from which the locking elements can be unwound during a closing movement, wherein the locking elements are preferably positively connected to the guide elements, in particular clamped to the guide elements.

[0017] In a simple and cost-effective method of creating a stable connection between the closure elements and the guide elements according to the invention, the guide elements, preferably formed in the form of winding shafts, can have a longitudinally arranged recess for inserting the closure elements. The recess can preferably include a tapered section for securing the closure elements. The longitudinally arranged recess can, in particular, be designed in the form of a slot or the like, into which a closure element can be inserted. The closure elements can then be easily fastened via a tapered section of the slot.

[0018] According to the invention, for the simple and stable guidance of the device in question, it can further be provided that the guide elements are arranged at the ends or outer regions of the device, the guide elements preferably being equidistant from the center of symmetry of the device. The guide elements, preferably formed in the form of winding shafts, are advantageously vertically oriented, with the first guide element or the first winding shaft being provided in particular for winding and unwinding the second closure element, whereas the second guide element or the second winding shaft is provided in particular for winding and unwinding the first closure element.

[0019] With a view to a space-saving and compact arrangement, as well as precise, effective and low-wear control of the locking elements during opening and closing movements, the invention provides that the control elements are formed in the form of shafts and cable pulls arranged on each shaft, preferably with one cable pull for the first control element and one cable pull for the second control element. The cable pulls can preferably be in the form of thin and strong wires, in particular fine stainless steel cables or the like.

[0020] For a particularly stable and robust design, the cables can also be in the form of Bowden cables or similar.

[0021] With a view to a space-saving, compact arrangement to ensure simultaneously effective ventilation and optimized aerodynamics, it is particularly advantageous if the first control element is connected to the second locking element and the second control element to the first locking element in such a way that the locking elements can be unwound from the guide elements during a closing movement, while the cables of the first and second control elements can be wound onto the first and second control elements.

[0022] With a view to maintaining a constant tensile stress on the locking elements during opening and closing operations, the invention further provides that the control elements have conically shaped sections for winding and unwinding the cables and fastening sections for attaching the control elements to the guide elements, wherein the diameter of the conically shaped sections preferably decreases from the outside to the inside in the direction of the fastening sections. The conization serves in particular to compensate for an increase or decrease in diameter caused by the winding and unwinding of the locking elements around the guide elements.

[0023] To ensure a stable attachment of the locking elements to the control elements, it is also conceivable that a first and second end strip are provided for attaching the locking elements to the control elements, wherein the control elements are preferably connected to the first and second end strips via the cables, the connection between the cables and the end strips being, in particular, positive-locking. The end strips can preferably be made of plastic and, in particular, be detachably connected to the locking elements. The end strips can preferably have receiving ridges for insertion into the recesses of the locking elements, and the end strips can preferably have a plurality of receiving ridges arranged one above the other.

[0024] As part of a structurally simple yet stable fastening of the closure elements to the end strips, it can be provided that the end strips have covers for fixing the closure elements to the end strips, wherein the covers preferably have corresponding recesses for the insertion of the receiving ribs of the end strips, wherein the connection between the covers and the end strips is formed in the form of clip connections. In this way, in particular, complex sewing processes, e.g., when fixing via piping or the like, can be avoided.
